To evaluate the perceived efficacy of a high-fidelity synthetic canine model for simulating common gastrointestinal surgical procedures.
Survey of students and experienced clinicians.
Twelve clinicians with >2 years of postgraduate experience in the field of small animal surgery and 102 senior year veterinary students.
The model was subjectively evaluated by 12 clinicians with >2 years of postgraduate experience in the field of small animal surgery. Senior year veterinary students (n = 102) were asked to complete questionnaires before and after a laboratory on common gastrointestinal surgical procedures that included rating of perceived proficiency, anatomical knowledge, and the use of synthetic models compared with live animals.
Clinicians assessed most aspects of the model as moderately realistic and unanimously agreed that it would be helpful for students to train on this model prior to live surgery. Student survey response rates were 91% and 99% before and after the laboratory, respectively. The proportion of students that felt moderately-to-highly proficient with the procedures increased from 8% prior to the laboratories to 59% after the laboratories (P < .001). The proportion of students that felt that they had superior-to-excellent knowledge of abdominal surgical anatomy increased from 16% prior to the laboratories to 44% after the laboratories (P < .001). The proportion of students that were satisfied with synthetic models instead of live animals increased from 52% prior to the laboratories to 74% after the laboratories (P = .014).
Experienced clinicians considered the model to have moderate realism. A positive shift in the students' self-perceived proficiency with gastrointestinal surgery was evident after the use of the model.
This synthetic model should be considered for training of veterinary gastrointestinal surgery. However, comparison studies are recommended to ascertain the relative educational value of this model.
评估一种高保真合成犬模型在模拟常见胃肠外科手术中的感知效能。
对学生和经验丰富的临床医生进行调查。
12名在小动物外科领域有超过2年研究生经验的临床医生和102名兽医专业高年级学生。
由12名在小动物外科领域有超过2年研究生经验的临床医生对该模型进行主观评估。兽医专业高年级学生（n = 102）在一次关于常见胃肠外科手术的实验室课程前后被要求完成问卷，问卷内容包括对感知熟练度、解剖学知识以及与活体动物相比合成模型的使用情况进行评分。
临床医生认为该模型的大多数方面具有中等逼真度，并一致认为在活体手术前让学生使用此模型进行训练会有所帮助。实验室课程前后学生的调查回复率分别为91%和99%。感觉对手术操作中等至高度熟练的学生比例从实验室课程前的8%增加到实验室课程后的59%（P <.001）。感觉对腹部手术解剖学有优异至卓越知识的学生比例从实验室课程前的16%增加到实验室课程后的44%（P <.001）。对合成模型而非活体动物感到满意的学生比例从实验室课程前的52%增加到实验室课程后的74%（P =.014）。
经验丰富的临床医生认为该模型具有中等逼真度。使用该模型后，学生对胃肠外科手术的自我感知熟练度有明显的积极转变。
应考虑使用这种合成模型来训练兽医胃肠外科手术。然而，建议进行比较研究以确定该模型的相对教育价值。
